Did you get any errors in console? How did you install the gamemode?

I installed the gamemode by first extracting the .gma with the GMAD.exe located in the bin folder. I then placed the newly created folder into a new server folder that only has ulib and ulx installed. I created a new start.bat and changed the server.cfg and mount.cfg to the correct specifications. Finally, I start the server with the .bat file. When I scrolled through the console I found the following errors/ things IDK what they are or do.

1. ConVarRef mat_dxlevel doesn't point to an existing ConVar.
2. HTTP failed - ISteamHTTP isn't available!
3. Attempted to create unknown entity type spawn_zone.
4.Can't init spawn_zone
5. Nav File is wrong or something (1)

With these errors only I am able to log into the server, but I am unable to see what I can only guess is the "spawn_zone", and I cant use bombs.

spawn_zone is the entity that defines where the grid goes, without it boxes can't spawn and you can't place bombs.

I don't know why the way you installed it didn't work.
Try downloading from https://github.com/mechanicalmind/melonbomber/releases , place the extracted zip in garrysmod/gamemodes/ so it looks like garrysmod/gamemodes/melonbomber

That link does not work.

the link included the comma. haha

Okay, here is the run down. I DL the top .zip file and installed the way you said and it did not work. After naming the .zip to melonbomber instead of melonbomber-(whatever the vs number was), and putting the map .bsp file into garrysmod/maps everything loaded correctly and I have the server working. After learning this I wondered if I could duplicate the result by putting the workshop version into the folder you described. after I did this the server stopeed working. I say this so that you might look into what the problem is with the workshop version. I put the files from github back into its proper place and it works still. Thanks for the help.
